分子别名（Synonym）:HA
 

种属（Species）：H1N1
 

表达系统（Expressed Host）：HEK293 Cells
 

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4
 

分子量（Molecule Mass）：The secreted recombinant Influenza A virus (A/California/04/2009 (H1N1)) HA (mutated) comprises 527 amino acids and predicts a molecular mass of 60 kDa. As a result of glycosylation and proteolysis, the apparent molecular mass of the hemagglutinin is apparoximately 25-30, 50-55 and 80-85 kDa in SDS-PAGE under reducing conditions, corresponding to the HA2, HA1 subunit and the full length HA respectively.
 

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.
 

生物活性(Activity)：
 

表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain of Influenza A virus (A/California/04/2009 (H1N1)) hemagglutinin (ACP41105.1) (Ser 2-Gln 529) with cleavage site mutated (IQS→RQRRRRK, HA1+HA2, partially cleaved) was expressed, with a C-terminal polyhistidine tag.
 

存储条件（Storage）：For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.  

运输条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
